To all whom it mag/concern:

Be it known that I, CHARLES .W. HARnoLn, a citizen of the United States, residing in the city of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Printing Presses, of which the following is a speciication, reference being made to the accompanying drawings, forming a part thereof.

My improvement relates more particularly to printing-presses in which there is also embodied a air of coacting cylinders for cutting, slittlng, or otherwise perforating the successive sheets of stock after same have been printed in the printing couple proper.

The objects of my invention are, among other things, to provide a simplified press of this type in which an intermediate transfer-cylinder is arranged between the printing couple and slitting couple combined with means for adjusting the transfer-cylinder or one of the cutting cylinders to properly register the sheet for the slitting operation after the printing in case the printing design on the plate cylinder is not exactly straight with such cylinder so that when the printing appears on the sheet, the side margins are not exactly parallel with the edges of the sheets; further to provide an automatic relay throw-olfl for the cutting cylinders so timed and coordinated with the impression throw-off for the printingl couple that the separation of the cutting cylinders is delayed until both sheets of stock in the press shall have completed their passage through the cutting cylinders, no matter when the press itself is tripped, either automatically from the absence of a sheet on the feed-board, or manually at some other part of the cylinder. such automatic relay mechanism taking care of the timing of such second throw-ofi' of the cutting cylinders until the last full sheet will be completely slit of' cut before the slitting or cutting cylinders separate: further to provide means for individual as well as collective adjustments of the cutting disks on the main shaft of the male cutting cylinder whereby the individual blades may be readily set to obtain accurate cutting or slitting; further to provide novel means for mounting suchindividual blades allowing for shifting or easy removal of same combined with means for procuring minute relative adjustments for the several blades, as well as separate blade adiustments in their individual carriers.

y improved printing-press also embodies other features of novelty and improvement 1n combination with a slitting, cuttlng or perforating attachment, whereby the operating mechanisms are simplified and made more effective and otherwise better adapted for use, al1 of which will be hereinafter set forth and then particularly pointed out in the appended claims.

The drawlngs show my invention in its preferred embodiment in a three cylinder offset press with the slitting cylinder attachment arranged with blades adapted to slit'or cut a sheet or strip of cardboard or similar stock with eight rowsv across the sheet requiring seven knives or blades in each row. Such layout for the cutting blades, however, may be widely varied to meet requirements. My improvements. however, are not to be restricted to any partlcular type of printing-press, since the invention may be embodied in various types with the same advantages and results.

Referring more particu arly to Fig. 1, the frame 22 supports the bearings for the form-cylinder 23, the rubber blanket-cylinder 24 and impression-cylinder 25, these cylinders being mounted on the shafts 26, 27 and 28 respectively. These three cylinders are so constructed and arranged in the frame 22 that the blanket-cylinder 24 forms a printing couple with the impression-cylinder 25, after receiving its design from the form-cylinder 23. The .respective cylinders have each fixed thereto suitable gears the pitch-diameters of which coincide with the peripheries of the respective cylinders. Referring to Figs. 18 and 21, the blanket-cylinder 24 carries the gear 29 adjustably secured to the cylinder 24 by screw bolts 30 passing through slots 31; the gear 29 enmeshes with the gear 32 adj ustably secured to the inipressioncylinder 25 by screw-bolts 33 passing throu h slots 34. Concentrically mounted on t e gear 32 is the slip-gear 35 which is adjustable on the gear 32 by the screw-bolts 36 passing throu h slots 37 (Figs. 18 and 19), the gear a so enmeshing with the gear secured to the shaft 53.

increases 29. Such arrangement of gears for thel blanket-cylinder 24 and impression-cylinder 25 takes u all looseness or play between the cylin ers resulting in accuracy in the printing operation. rlhe gears for t ree c linders 23, 24 and 25 intermesh to form t e drivin mechanism to secure the proper rotation o these cylinders in the directions shown by the arrows on the three c linders in Fig. 1. Power is derived from t e main driving shaft 38 carrying the pinion 39 in engagement with the gear 29.

The shaft 27 carrying the blanket-cylinder 24 is mounted at both ends in the eccentric bearings 40, which, in turn, are mounted in ournals 41 secured to the frame 22. 'lihe earings have arms 42 rejecting from flanges on the outside of t e frame 22 as shown on one side thereof, such arm 42 being connected to the arm 43 secured to the 'spring-im elled throw-off shaft 44 by the link 45, t e shaft 44 being rocked by the spring 46 in the direction of the arrow shown in Fig. 2 to pull the link 45 and arm 42 to the right to separate the blanketcylinder 24 from both form-cylinder 23 and impression-cylinder 25 to throw off the printing impression. A reverse movement of the link 45 will restore the impression by rotating the shaft 44 in a clockwise direction by a hand lever which is not here shown since such device is well-known in the art.

lin order that this impression throw-ofi1 and throw-oli mechanism may be automatically actuated in case of the failure of the feed of a sheet to the press, i have devised the following mechanism shown in Figs. 1 and 2: The feed-table 47 is secured to the frame 22 whereon the successive sheets may be advanced to the impression-cylinder 25 as shown in Fig. 1. Extending transversely in the frame 22 is the throw-01T shaft 44 which is oscillated by the spring 46 as heretofore described. rlhe shaft 44 is held in the position shown by the latch 48 secured to the shaft 49 journalled in the frame 22 and extending across the' feed-table 47 as shown in Fig. 2. rlhe latch 48 engages with the notch 50 in the collar 51 mounted on the shaft 44. Preferably this latch 48 is released automatically through trip mechanism on the feeder: The feed-table 47 supports the. stock 52 that is being fed to the press. Extending transversely above the `feed-table 47 and journalled in uprights at the sides thereof is the shaft 53 which carries the arm 54 (Fig. 1) connected by the link 55 to the crankpin 56 on the impression-cylinder shaft 25 so as to impart to the shaft 53 an oscillating inove ment. 57, 57 are two grooved collars rigidly Adjacent each grooved collar 57 is the disk 58 affixed to the inner end of the tubular shaft 59 which is loosely sleeved on, and encloses a portion of, the shaft 53 as shown in Fig. 2. The

lll() I tubular shaft 59 carries the arm 60 having the projecting lug 61 which engages with the arm 62 secured to the shaft 49. The triplever 63 is pivoted at 64 between the parallel sides of thc grooved collars 57, so that'its longer and heavier arm is held from fallmg into the-aperture 65 cut in the top of the feed-table 47 by the interposition of the stock 52 as shown in. Fig. 2. The opposite end of the lever 63 is T-shaped to lform the laterally extending tooth 66; in the pcripheries of the collars 57 and also of the disk 58 are formed cut-outs 67 and 68 respectively. Ordinarily the tooth 66 rests against, or is in proximity to, the periphery of the disk 58; it can engage with the cut-out 67 of the collars 57 only when it can fall into the cut-out 68 of the disk 58. When this occurs the disk 58 with its tubular shaft 59, which are vnormally at rest, are locked to, and turn with, the oscillating shaft 53. The entrance of this tooth 66 into locking en agement with the disk 58 will occur upon t e failure or interruption in the feed supply. When the stock 52 is in proper position as shown 1n Figs. 1 and 2, the curved longer arm of the tr1p lever 63 will engage therewith and w1ll be prevented from lowering into the aperture 65, and from turning sufficiently to interlock the disk 58. If the stock 52 should, at any time, be interrupted or absent, the longer arm of thetrip-lever 63 will fall of its own weight into the aperture 65, thereby causing the tooth 66 to interlock with the cut-out 68 of the disk 58. Thus the tubular shaft 59 will be caused to oscillate with the shaft 53 to lift the arm 60 to release the latch 48 engaging the notch 50 in the collar 51 on the shaft 44. Through this movement ofthe herein described mechanism the shaft 44 is partially rotated by the spring 46 to throwoff the impression by se arating the blanketcylinder 24 from the crm-cylinder 23 and impression-cylinder 25, all controlled automatically by the stock.

Means are provided to adjust the position of the impression-cylinder 25 with relation to the blanket-cylinder 24 to accommodate sheets of stock of different thickness: Referring to Fig. 1 the impression-cylinder shaft 28 is mounted at both ends in eccentric bearings 69, which, in turn, are mounted in journals 70 secured in the frame 22. The bearings 69 carry the arm 71 projecting from flanges outside the frame 22, as shown on one` side thereof, and the screw-bolt 72 carried by the arm 71 and passing through curved slots 73 enable adjustments of the impressioncylinder 25 by moving same horizontally to and from the blanket-cylinder Withoutdisturbing its relation to the transfer-cylinder 74 mounted on the shaft 75 journalled in the bearings 76 horizontally slidable in the frame 22 by the adjusting screws 77 and 78. The transfer-cylinder 74 carries the Successive printed sheets to the Afemale cutting cylinder 79 mounted on the shaft 80 'ournalled in the bearings 80a vertically sli able 1n frame 22 by the adjusting screws 80b and 80,.Wh1ch cylinder 79 coacts with the male cutting-cylinder 81 to form a slitting or cutting couple: the sheets are taken by the dellvery cylinder 82 and intermediate cylinder 83 tothe delivery-mechanism 84. Referring to Flg. 18, the cutting cylinder 79 adjustably carries the gear 85 Which meshes with both the slip gear 86 and the main gear 87 adjustably mounted on the cylinder 81, the sbp-gear 86 being adjustable on the gear 87, such arrangement of gears for the cylinders 79 and 81 with screw-bolt and slot devices for adjustment having been heretofore de- 'scribed with reference to the blanket-cylinder 24 and impression-cylinder 25 respectively. The cuttlng cylinders 79 and 81 are'rotated by means of the pinion 88 in mesh with the gear 85 and pinion 39 on the main driving shaft 38. l

n Referring to Figs. 3 and 15, the male cutting cylinder 81 is preferably composed of a series of disks -89 slidably mounted on the shaft. 90 of the cylinder 81, and preferably secured thereto by set screws which are not shown. Each disk- 89 has formed therein a clearance hole 91 to receive a transverse screw-threaded rod 92 on which screw-nuts 93 and 94 are carried on either side of the several disks 89 as shown in Figures 3 and 15. Means are preferably employed to collectively adjust the several disks 89 on the shaft 90, which means may be widely varied in construction. In the present embodiment, two bearing disks 89a are. pinned fast to the shaft 90 at either end as shown in Fig. 3, each disk 89a having a clearance hole through which the ends of the rod 92 project, such rod carrying the nuts 93a and 94av on either side of the disks 89a as shown. When it is desired to collectively adjust the disks 89 as a unit, the two sets of nuts 93 and 94a are manipulated to shift the rod 92l transversely in either direction, while a group adjustment of several disks 89 is attained by loosening the nuts 93 and 94 of the remaining disks and then tightening same after the first set of disks has been shifted as a group. Each disk 89 may be separately adjusted relatively to its adjacent disks by the sets of nuts 93 and 94- on either side of the disk to be shifted.

Other means for collectively yadjusting the disks 89 may be employed, as for example,lplacing keyed washers and threaded collars on the projecting threaded ends of the shaft 90 outside the frames 22 which will shift the entire cylinder 81 laterally as a unit in the direction desired.

Separate means are provided to throw off the cylinder 81 from the cylinder 79. Accordingly the shaft 90 for the male cutting cylinder 81 is mounted at both ends injeccentric bearings (Figs. 1 and 3) which, in turn are mounted in journals 96 carried by the frame 22. The bearings 95"carry the projecting arms 97 (Fi 3) to which 1s 1votally secured the togg e levers 98 pinne at 99 to the to gle arms 100 mountedbn the throw-ofi' s aft 101 journalled 1n the brackets 102 secured to the frame 22 as shown in. Fig. 3.

An im ortant feature of my mventlon 1s to provi e an automatic relay mechanism by which the impression throw-oft" for the printing couple inaugurates andcontrols the throw-od' for the cutting or slittlng cylinders in predetermined sequence with the 1mression throw-0H, so that each of the sheets 1n the press at the time the press 1s tripped (either automatically or by hand) may be fully printed and thereafter slltted or cut by the cylinders 79 and 81 before the llatter cylinders separate. Referring to Figs.. 1 and 3 and to detail Figs. 4 to 12 lnclusiye, 1 have devised a relay mechanism by which the separation of the cutting cyllnders 79 and 81 is delayed, after the separatlon of the cylinder 24 from the cylinders 23 and 25, until the last sheet properly fed to the press has completely passed through the cutting1 cylinders, such relay mechanism automatically taking care of the timing of such second throw-ofi1 of the cylinders 79 and 81 until this last full sheet has been completely slit or cut by such cylinders. Such relay mechanism is described as follows: The throw-od shaft 101 on one side of the frame 22 as shown in Fig. 3 carries two coacting cam-arms 103 and 104 mounted on sleeves 105 and 106 respectively, both being journalled on the shaft 101. Between the two arms 103 and 104 is arranged the cam 107 secured to the cylinder shaft 90; the arms 103 and 104 carry the cam-rollers 108 and 109 respectively to engage with the cam 107 by means of the spring 110 connecting the arms 103 and 104. ln the normal operation of the press the arms 103 and 104 are idlin and arel rocked up and down by the cam 10 in scissor-like fashion, the spring 110 main'- taining the rollers 108 and 109 always in contact with the cam 107 with the arm 103 always above and the arm 104 -always bev low the low part of the cam 107.

Referring more particularly to Figs. 4. 5 and 6 the sleeve 105 carries the bracket.- 111 on which the pawl 112 is pivoted; the pawl 112 has extending outwardly therefrom the pin 113 on which the cam-roller 114 is rotatably mounted to ride on the top of the cam-plate 115 journalled on the shaft 101. Adjacent the cam-plate 115 and pinned thereto is the rock-arm 116 journalled on the end of the shaft 101 and secured thereto by the washer 117. lnwardly and adjacent the sleeve 105 the single-tooth Lacasse ratchet-plate 118 is arranged beneath the pawl 112 and is pinned to the cam-plate 1.19, both ratchet and cam being journalled on the shaft 101 and arranged thereon betweenl the sleeves 105 and 106 as shown'in Fig. 6. 'lhev cam-plate 119 carries the transverse rod 120 which projects outwardl and extends through the slot 121 formed 1n the rock arm'116 as shown in Figs. 6 and 7. llnwardly adjoining the sleeve 106 is the single-tooth ratchet-plate 122 mounted on the shaft 101 andi4 is also pinned to the collar 123 which is secured tthe shaft 101 by the bolt 124, the collar 123 also carrying the hand-lever 125, as shown in Figs. 5 and 6. 'llhe sleeve 106 carries the bracket 126 (Figs. 5 and 11) on which the pawl 127 is pivoted to coact with the ratchet-plate 122. Extending outwardly from the pavvl 127 is the pin 128 (Fig 5), on which is rotatably mounted the cam-roller 129 which is adapted to ride on the top of the cam-plate 119. 'llhe lower end of the lrock-arm 116 has pivoted thereto the link 130 which is also pivotally secured by the pin 131 to the arm 42 projecting from the eccentric bearings 40 for the blanket-cylinder 24.

Means are providedfor mounting the individual sets of knife blades or cutters on the cutting cylinders 79 and 81 which are shown in detail in Figs. 13 to 17 inclusive, whereby the individual blades may not only be easily removed, but also be secured on the cylinder 81. by means admitting of minute relative adjustments. Referring to Figs 15 and 16, the disks 89 on the male cutting cylinder carry the split housings 132, the successive housings 132 being adj usted relatively to one another by the screws 134 (Fig. 16). Fach housing 132 has the cut-out 135 formed in its outer surface to contain and hold'the transverse cutter blades 136 maintained between the clamp blocks 137 and 138. The block 138 has a bevel surface 139 on which the wedge block 140 slides inwardly to bind the blades 136 between the blocks 137 and 138. The block 140 has a hole bored therein through which the screw-bolt 141 extends to engage with the housing 132. rlhe spring 142 is coiled around the bolt 141 and tends to force the wedge block 140 outwardly. The inward movement of this block 140 by screwing in the holt 141 against the spring 142 binds the blades 136 in position. The longitudinal cutter blades 143 are carried in a suitable groove 144 formed `in the periphery of plates 158 on the disks 89, and are adjusted relatively toone another in the grooves 144 by the screws 159 (Fig. 17). The female cutting cylinder 79 has formed in its outer surface circular parallel run-ways 145 in which are adjustably secured the groove bedplates 146 toi coact with the longitudinal Elli cutting blades 143: in like manner the grooved-bed-plates 147 are also adjustably secured to tht` cylinder 79 to receive the transverse cutting blades 13G. all as shown in Fig. '17. The collective arrangement of the two sets .of cutting blades 136 and 143 in relation to the female cutting cylinder 79 is shown in Figs. 13 and 14.

In order that the transfer-cylimler 74 may transmit the printed sheet from the ihmpression-cylinder 25 to the cutting cylinder 79 so that such sheet may be positioned and timed to secure great accuracy in the slitting operation, I have devised means whereby coacting register racks are adjustably carried by the cylinders 74 and 79 at the time the sheet is transferred which are best shown in Figs. 18 to 20: The gear 148 co-acts with the gear 32 and gear 85, and is adjustably mounted on the transfer-cylinder 74'by screw bolts 149 passing through washers' 150 and slots 151. The Iteeth on this gear 148 are undercut considerably so that it is not driven by the gear 32 except when the register rack 152 adjustably secured to the gear 148 by screw-bolts 153 passing through slots 154 (Figs. 18 and 20) is in mesh with the gears 32 and 35 on the impression-cylinder 25 while receiving the sheet from such impression cylinder 25. At other periods in the rotation of the cylinder the gear 148 practically floatsbetween the impression-cylinder gears and the gear 85 on the cylinder 79 until the register rack 152 meshes with a similar rack 155 adjustably secured to the gear 85 by bolts 156 passing through slots 157 in the same manner as the rack 152 is mounted on the gear 148 (Fig. 20). By this mechanism the coacting register racks 152 and 155 fully control the timing of the transfer-cylinder 74 at both periods when receiving the sheet, and thereafter when delivering same to the female cutting cylinder 79.

The operation of the hereinbefore described mechanism is substantially as follows: Whenever the stock 52 is interrupted or is absent from the feed-table 47, the triplever 63 acts to release the spring-impelled shaft 44 which pulls the link 45 to the right as indicated by the arrow in Fig. 1, thereby swinging the arm 42 also to the right to separate the blanket-cylinderv 24 from both form-cylinder 23 and impression-cylinder 25 to throw-oil" the impression. When the arm 42 moves to the right it simultaneously pulls the link 130 with it in the direction of the arrow thereby shifting therock-arm 116 and its attached cam-plate 115 from the position shown in Fig. 4 to that shown in Fig. 7. This anti-clockwise movement allows the pawl 112 to engage the tooth in the ratchet-plate 118. At the next upward movement of the arm 103 by the cam 107 on the cylinder-shaft 90 the ratchet-plate 118 is swung to the left as shown in Fig'. 9 thereby moving the camplate 119 from the dotted line. to the full line position shown in Fig. 9. This movement will cause the cam-roller 129 to ride olf the high part of the cam-plate 119 and the pawl 127 will engage the tooth on the.

95 to separate the male cutting cylinder 81 from both the female cutting cylinder'79 and delivery-cylinder 82. The hand lever 125 may also be used to throw-ofi' the cutting cylinders independently of the impression t row-off, and this hand lever 125 is also used to restore the cutting cylinders to operative position. The hand-lever (not shown) on the shaft 44 may also be used to restore the impression' lthrow-ofi?, reset the latch 48 for the automatic trip mechanism, and raise the pawll 112 out of engagement with the ratchet 118 so that the arms 103 and 104 are again free to be raised and lowered by the cam 107 without inaugurating the relay mechanism for the throw-off of the cutting-cylinders.

By this construction I have devised two automatic sequential throw-offs for the printing couple and slitting couple, the second throw-off being positively actuated by means operable through the continued movement of the press, the cutting or slitting cylinder throw-off being controlled, but not operated, by the impression throw-olf with the timing of such second throw-oil being delayed until both sheets in the press will have passed completely through the cutting cylinders before thelatter are separated, no matter at what part of the cycle the impression of the printing couple is thrown-olf either automatically by the feeder-trip devices or manually by the operator.

The horizontal sliding bearings 76 for the transfer-cylinder 74 at both ends thereof provide a ready means for allowing for any inaccuracy of the printing design on lthe form-cylinder 23, such inaccuracy being thereafter carried forward to the cutting cylinders 79 and 81 with a similar inaccuracy in the cutting margin. By properly adjusting one or the other of such slidable bearings 76, the sheet is delivered by the cylinder 74 to the cutting cylinder 79 so that the printed design is square with the cylinder, and the knife cuts made by the blades 136 and 143 fall in proper register with the printed margin of the sheet; in like manner the cylinder 79 may be vertically adjusted by shifting the bearings 80a for the same purpose.
